NURSING-BOTTLE NIPPLE.

SPECIFICATION forming part of Letters Patent No. 497,994, dated May 23,1893. Application filed November 30, 1892. Serial No. 453.617. (N0specimens.)

To all whom it may concern.-

Be it known that I, LOUIS B. TRUSLOW, of Milburn, county of Essex, Stateof New Jersey, have invented new and useful Improvements inNursing-Bottle Nipples, of which the following is a specification.

The accompanying drawing represents an ordinary nursing bottle lying onits flat side having a nipple applied, constructed according to myinvention.

A is the bottle. B is the nipple made of soft vulcanized rubber andtherefore pliable and compressible. It consists of a cap 1) adapted tofit over the mouth of the bottle, which cap is extended forward andthence on a downward inclination, as shown. The nipple decreases indiameter gradually as it extends beyond the mouth of the bottle formingthe neck I). b is a head integral with the neck constructed of the formshown. That is to say, it enlarges abruptly from the neck at c and thencontracts more gradually to the end where is the hole from whichnourishment is supplied to the infant.

The following principal advantages may be mentioned: The downwardcurvature of the nipple brings its extremity in convenient position foruse and at the same time provides a receptacle lower than the bottleinto which liquid nourishment will always run of its own gravity so asto keep the outlet hole submerged and prevent air being swallowed. Theacorn shaped head provides a gradual enlargement from the point thatmakes the head readily inserted into the mouth and also provides anabrupt shoulder at c that makes it more difficult of removal from themouth.

I am aware that nipples have been constructed provided with a cap to fitover the head of the bottle and extending forward with decreasingdiameter, but without aXi-alcurvature. I am aware that bottle stoppershave also been provided with a tube extending through the stopper andcontaining outside, a curvature terminatingin a nipple. ldo notclaimsuch contrivances, in all of which the construction is such that themilk fails to flow freely and without obstruction through the neck ofthe bottle and thence to a lower level in the nipple. In my inventionwhenever the bottle is in such position as to permit of milk flowingthrough the neck, it will inevitably fill the tip of the nipple andprevent the consum ption of air. My nipple is made, as shown, to fitover the head of the bottle and thus avoid any obstruction within theneck of the bottle and to project forward from the neck of the bottlesubstantially at or below the lower level of the same and downward tothe tip, whereby the milk will always run into the tip of the nipple andthe air will accumulate in the back of the bottle instead of in thenipple as heretofore. My nipple is therefore applicable to any of theordinary straight necked bottles in use.

I claim As an article of manufacture,a nursing bottle nipple of softrubber comprising a cap adapted to tit outside the mouth of the bottle,a laterally curved neck and head all in one piece,having its lower levelat or below the level of the bottle neck, whereby the milk may flowwithout obstruction through the neck of the bottle and thence downwardto the tip of the nipple, substantially as described.
